How this is calculated

ROI is simply (final value − initial investment) / initial investment. That number alone can be misleading when comparing investments held for different lengths of time — a 50% return over 5 years is very different from a 50% return over 6 months. When you give the number of years, we also compute the annualized ROI: the constant yearly rate that would produce the same total return, using the same formula as CAGR.
